To all whom it may concern:

Be it known that 1, MAX JOSEPH Hmson, subject of the King of Saxony, residing at Zurickauerstrasse 58, Schonau, near Chemnitz, Saxony, Germany, have invented certain new and useful Improvements in Machines for Pressing Knitted Garments, of which the following is a specification.

My invention refers to the manufacture of garments of all kinds made of knitted stocking-material or jersey-cloth, either woolen or cotton or silk, and more especially to the finishing treatment by pressing, such treatment consisting in subjecting the finished garments to hydraulic pressure, the garments being placed to this end between press-boards and hot iron plates heated byv steam or other means. The treatment described is rather cumbersome, requires a great amount of hand-work and is not economical, especially so in smaller factories where the quantity of garments manufactured during a day is not great enough to completely fill out the room available in the press, so that in these cases the empty space must be filled up with blocks or plates of wood. Moreover the considerable weight of the piles of superposed press-boards and garments renders their handling and introduction into the press rather difficult.

It has been attempted to render the pressing procedure easier and more economic by employing continuously working presses comprising a pair of pressing plates, the upper one being stationary and heated by suitable means, while the lower one could be pressed against it from below by aid of a toggle lever arrangement, said lower plate swiveling sidewise so as to allow the piles to be placed upon it. \Vith these devices only one pair of garments is treated at a time, so

that they cannot be considered to be more economical than the old presses.

The garments after being placed between press-boards have been passed through a pair of pressure-rollers. The particular object of this invention is an improvement of the last mentioned device, and it consists of a machine comprising a pair of pressurerollers adapted to exert heavy pressure upon a pile of garments and press-boards, and heating plates and feed rollers arranged in front of and behind the pressure-rollers in such a way that the piles on being introduced into the machine by hand will automatically pass through the feedand pressurerollers and over the heating plates placed in front of and behind the said pres sure-rollers.

The machine above described presents a very high efficiency, the work done with it being continuous and furnishing highly satisfactory results as far as the pressing and smoothing of the fabric is concerned, 'the garments thus treated retaining the high reduction of thickness most favorable for packing. No other machine employed up to date will furnish equally good results in this respect.

In the drawings accompanying this specification and forming part thereof the pre ferred form of a machine according to this invention is represented diagrammatically, Figure 1 being an elevation, and Fig. 2 a plan; the machine bed is not shown in both cases. 7

Referring to the drawings, 9 g are tables for feeding the piles of garments a and press-boards 1) into the machine proper.

0 and c 0 are two pairs of feeding rollers, 6 e are a pair of pressure-rollers adapted to be pressed against each other bv mechanical or hydraulic pressure, and (Z (Z2 and d (Z* are two pairs of superposed plates, at least one pair being heated by aid of steam or the like, the distance between the plates of each pair being equal to the thickness of a pair of press-boards and the garment or garments placed between them. The inner surface of the said plates is smooth. The pressure-rollers are made either of metal or of an elastic material such as pressed paper, cotton, jute or the like. The lower roller is driven by suitable gearing, while the upper roller is arranged to bu displaced vertically and to be set at different levels.

A pair of press-boards and the garments placed between them are fed into the feeding rollers 0 c and from there between the hot plates (Z (2 where the boards are heated. On leaving the plates the boards pass between the pressure-rollers e 6 the garments being there subjected to pressure between the hot plates, and on leaving said rollers are passed between another pair of plates 6Z3, (Z in order to be ultimately gripped by the second pair of feeding rollers 0 0* and to be deposited. on the table 9 which can be arranged to be lowered automatically l. A machine for pressing knitted garmentscomprising a pair of pressure rollers and two pairs of heating plates and feeding rollers arranged in front and rear of said pressure rollers respectively.

2. In a machine of the class described, in combination, two pairs of feeding rollers, two pairs of superposed heating plates arranged between said pairs of feeding rollers and a pair of pressure rollers arranged between said pairs of heating plates.

3. In a machine of the class described, the combination of two parallel plates spaced apart a distance equal to the thickness of two press boards and the material to be pressed between them, means for feeding such boards and material through said space, and a pair of pressure rolls arranged at the out- Gopies of this patent may be let end of saidspace and between which the boards and intermediate material pass.

4:. In a machine of the class described, the combination of a table like support for press boards and material to be pressed, a pair of parallel plates spaced apart a distance equal to the thickness of two press boards and the material to be pressed thereby, rolls arranged to feed a pair of press boards and material to be pressed thereby between said plates, and a. pair of pressure rolls for acting on the press boards.

5. In a machine of the class described, the combination of two pressure rolls adapted to receive a pair of press boards and the material to be pressed thereby, means for feeding the boards and material between the rolls, and means intermediate the feeding devices and pressure rolls for heating the material.

In testimony whereof I aflix my signature in presence of two witnesses.
